Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
...Negative tropism is a change in text of a song due to mishearing the lyrics or inaccurate memory of the lyrics. It results in multiple versions of songs after a while. It is very common in English and Scottish balladry, as well as in Appalachian ballads.
Leaves exhibit positive phototropism, which means they grow towards sources of light. This type of tropism allows leaves to maximize their exposure to sunlight for photosynthesis.
Positive gravitropism, where the plant roots grow in response to gravity by growing downward. This helps the roots anchor the plant and seek out nutrients and water in the soil.
The type of plant tropism that involves growth toward a stimulus is called "positive tropism." An example of this is phototropism, where plants bend toward light sources to maximize photosynthesis. This response is driven by differential growth rates on the sides of the plant, allowing it to optimize its exposure to sunlight. Other examples include gravitropism, where roots grow downward in response to gravity.
The phenomenon of a plant stem turning toward the sun is known as phototropism. This type of tropism occurs as a response to light stimuli, where the plant grows towards the light source to maximize photosynthesis. Auxins, a class of plant hormones, play a key role in this process by promoting cell elongation on the side of the plant that is away from the light.
positive gravitropism
Positive geotropism is where the roots grow towards gravity.
photo tropism is the growth-response to light in a plant. stems exhibit positive photo tropism while most roots exhibit negative photo-tropism
A positive tropism is something that bends with gravity or bends towards the light or the roots grow towards water. A negative tropism does the exact opposite.

Roots exhibit positive gravitropism, growing downwards in response to gravity. They also show positive hydrotropism, growing towards moisture to optimize water uptake. Additionally, roots demonstrate negative phototropism, avoiding light to remain underground where they are protected.
Stimulus is any kind of change in substances or in happenings, occurs in the surrounding of a living thing that bring about any kind of response from it.Tropism is the way by which plants respond to the stimuli. These kind of plant responses are either MOVEMENTS OR GROWTH of plat parts in particular directions.For Eg:-1. Leaves of 'touch me not plant' folds its leaves on our touch.2. plant roots grows towards the direction water availability.
Iris grows towards the light. That is phototropism.
Leaves exhibit positive phototropism, which means they grow towards sources of light. This type of tropism allows leaves to maximize their exposure to sunlight for photosynthesis.

Roots don't have roots, plants have roots.
Positive gravitropism, where the plant roots grow in response to gravity by growing downward. This helps the roots anchor the plant and seek out nutrients and water in the soil.
